An analysis of the gibberellic and abscisic acid content of white ash seeds

Journal of Arboriculture 10(10): 283-285
An analysis of the gibberellic and abscisic acid content of white ash seeds
Fraxinus americana seeds, 1-10 yr old, were analysed using high performance liquid chromatography. The youngest seeds had the highest GA content which then decreased rapidly. The greatest concn. of ABA was found in 4-yr-old seeds. Pericarps were removed and seeds of varying ages soaked in distilled water or GA sol. (at concn. just high enough to overcome the inhibitory effects of endogenous ABA) and germinated.
